Part No. RP1 | Compatible Instrument: Dwyer 485B
The Dwyer RP1 is a wired probe accessory for the Dwyer Model 485B base unit, extending its measurement capability to humidity and temperature, along with derived dew point and wet bulb readings. It measures relative humidity across the full 0–100% RH non-condensing range, with ±2% accuracy at 25°C. Accuracy is ±4% at the extreme ranges below 10% RH and above 90% RH.
Temperature measurement covers -20 to 140°F (-29 to 60°C), with ±0.54°F accuracy. An 8-inch insertion depth suits standard duct or space monitoring applications, while the rubber-overmolded housing and protective caps help protect the probe between uses.
When paired with the Dwyer 485B, the RP1 supports manual and automatic data logging. CE and RoHS approval supports standard compliance requirements.
